Pitambari is very good product in cleaning copper and bronze articles, few years ago I used to work as priest in sri rama temple in hyderbad, after performing poojas in the temple the articles used in pooja like kalash, treetha patra, arathi plate, bell etc were get dirty, dust. we have make lot of efforts to clean these pooja articles . but with the use of pitambari powder with minimum efforts we are able to clean the pooja articles very neat and clean.regular cleaning with pitambari powder make article shiny, new look.it is must for every temple in order to maintain the pooja articles clean, neat and shiny like new. I recommend this product for every temple
